绿色氢即将成为主流

中国石化新闻网讯 据今日油价网站3月19日消息 氢作为传统化石燃料的一种可行的绿色替代品，甚至作为商业融合的潜在解决方案得到了广泛关注，通常被称为清洁能源的圣杯。氢可以作为无数不同工业过程和内燃机的燃料来源，当其燃烧时，只留下水蒸气。然而，尽管它引起了很多轰动，但并不是所有种类的氢都是真正的绿色选择。事实上，很多氢是由化石燃料产生，主要是天然气和煤，这意味着它的使用实际上没有减少排放，这种被称为“灰色氢”的氢已经被用于工业和工业过程，如氨的生产、炼油厂和作为化工原料。

这就是为什么绿色氢如此重要的原因，不仅是氢部分，而且在制造过程，无论是在供应链的生产端还是消费端，都是零温室气体排放。唯一的问题是，我们还没有找到一种经济上可行的方法来生产绿色氢，而不需要使用大量资金或数吨能源投入，但目前我们已快接近这个门槛。

一方面，绿色氢的特性已经引起了很多投资者的关注，最近甚至连石油巨头都在通过新的可持续氢项目走向更绿色的市场。就在上个月，荷兰皇家壳牌公司宣布参与了一个绿色氢项目，涉及荷兰北海的一个海上风电场。

此外，专家预测，将绿色氢推向市场的最大障碍是资本成本的降低。Recharge News上个月报道称：“每个人都在预测成本曲线会下降，就像太阳能和风能一样。”这篇题为《为什么绿色氢是全球能源转型的关键》的文章继续写道：“不过，要想让价格点正确，必须达到规模经济。那么，这只是一个行业何时准备采取下一步行动的问题。壳牌等主要企业的参与已经让我们接近了这个门槛。”

Green Hydrogen Is About To Go Mainstream

Hydrogen gets a lot of attention as a feasible, green alternative to traditional fossil fuels, and even as the potential solution to commercial nuclear fusion, often referred to as the holy grail of clean energy. Hydrogen can be used as a fuel source for myriad different industrial processes and combustion engines, and when it burns it leaves nothing behind but water vapor. Sounds great, right? While it gets a lot of buzz, however, not all kinds of hydrogen are really a greener option. In fact, a lot of hydrogen is produced by using fossil fuels, primarily natural gas and coal, which means that its use really isn’t cutting down on emissions at all. This kind of hydrogen, called “gray hydrogen,” is already used in industries and industrial processes such as ammonia production, in refineries and as a feedstock for chemicals.

This is what makes green hydrogen such a big deal - not just the hydrogen part, but also how it’s made, with zero greenhouse gas emissions on either the production or the consumption end of the supply chain. The only issue is that we haven’t yet found an economically viable way to produce green hydrogen without using tons of cash or tons of energy inputs. But we’re getting close.

For one thing, green hydrogen’s buzzworthy nature has gotten a lot of attention from investors, and recently even supermajor oil companies have been heading for greener pastures with new sustainable hydrogen projects. Just last month Royal Dutch Shell announced their involvement in a green hydrogen project involving an offshore wind farm in the Dutch North Sea.

What’s more, experts are predicting that the biggest obstacle to bringing green hydrogen to market--its capital cost--is about to come down. “Everybody is predicting that the cost curve will come down, just as it has with solar and wind power,” Recharge News wrote last month. The article titled “Why green hydrogen is key to the global energy transition” continues: “Though, to get the price point right, you have to reach economies of scale. Then it’s just a matter of when the industry is primed to take the next step.” involvement from major players like Royal Dutch Shell is already getting us closer to that threshold.
